Perhaps you should try some spelling variations:
"using computational using subsampling program" » "and computational using subsampling program" (Expand search), "using computation using subsampling program" (Expand search), "using computations using subsampling program" (Expand search), "using computacional usinas subsampling program" (Expand search), "using computational using sampling program" (Expand search), "using computational and subsampling program" (Expand search)
"using map coding python programming" » "using map codigo python programming" (Expand search), "using map codigos python programming" (Expand search), "using map using python programming" (Expand search), "using maps coding python programming" (Expand search), "using map encoding python programming" (Expand search), "using map3k coding python programming" (Expand search), "using mass coding python programming" (Expand search), "using mask coding python programming" (Expand search), "using mean coding python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational using subsampling program\") OR (\"using map coding python programming\"))~".
• Removing quotes may allow a broader search: (( using computational using subsampling program ) OR ( using map coding python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational using subsampling program") OR ("using map coding python programming"))*.
